Lybster pick-up arrangements. |
On the right side of the engine all the wheels, both drivers and bogie, are shorted out with a wire soldered between the tyre and the brass centre boss. Pick-ups on the left side are wipers bearing against the back of the wheels and mounted on copper clad insulation board. The bogie pick-ups can be seen clearly above, the red wire is soldered to a metal tab which is screwed to the copper clad and is easily removable. The screw goes through a hole larger than itself in the metal mount to which the CCIB is glued. The red wire leads to another piece of CCIB near the motor from which it is also dismountable.

Base of roof in place |
The bunker and cab rear unit is held in place on the footplate with two screws inside the bunker, the roof, of which only the base is in place above, will be attached to the cab rear and will slot into a tongue on the top of the cab front plate.

Domed roof and jig. |
The domed roof was constructed from four triangular pieces of 0.4 n/s with the help of the jig on the right. When all four pieces were accurately lined up on the jig they were soldered together using thin paper as a barrier to prevent the roof being soldered to the jig. The roof was then removed from the jig, squared up and finished with files and abrasive paper.

Lybster with domed roof in place. |
A raised edge to form a rain channel and a transvers strengthening strip need to be added to the roof before it is complete. The backhead can be seen in place inside the cab, the flywheel fits neatly inside this, however it had to be made a little slimmer before it would fit inside on my mate Bob Goodyear's lathe.
The backhead itself is constructed from a Lochgorm Kits etch, it fitted well and needed no alteration, it's a good starting point and will be detailed with LGM components which are on order.
